生长季节长度对叶性状的影响进行了研究，发现沿着高山融雪梯度（无雪期为69至117天），并在四个落叶树种发现沿着海拔梯度（范围从140米至1900米）在北方日本。沿着这些梯度，叶寿命普遍下降，而比叶面积（SLA）和氮浓度（叶氮）增加，随着生长季节的缩短。各树种叶片寿命与叶片比叶面积、叶片氮含量均呈负相关。叶片比叶面积与叶片氮含量呈正相关。在短生长季节条件下，生产具有较低初始碳投资（叶片建设成本）的高氮叶片被认为是维持碳平衡的一种反应。
Effects of growing season length on leaf traits were studied in three deciduous species found along an alpine snowmelt gradient (snow-free period ranging from 69 to 117 days), and in four deciduous species found along an altitudinal gradient (ranging from 140 m to 1900 m) in northern Japan. Along these gradients, leaf life-span generally decreased while specific leaf area (SLA) and nitrogen concentration (leaf N) increased with a shorter growing season. In each species, there was a negative correlation between leaf life-span and SLA, and between leaf life-span and leaf N, respectively. A positive correlation was found between SLA and leaf N. Production of high nitrogen leaves which had a lower initial carbon investment (leaf construction cost) was considered to be a response to maintain the carbon balance under the condition of a short growing season.
